If they call you hang up!!! Then text them back starting with *67 to block your number. You have to text them because the have a stupidly long answer message that tells you to wait until they transfer your call to an agent WHICH NEVER HAPPENS AND THEY JUST HANG UP ON YOU!!
BUT if you text them it goes through:-) So tell them what they are and where to go:-)
This is a new number for me. Nobody answered when I said hello.
REMEMBER: If you call them back the DNC List is nullified! That's considered contacting them, so they can call you over and rode roar the next three months.
